Schneider Electric EM6400NG Modbus register map

Also searched as: EasyLogic EM6400NG · EM6400 NG

424 Modbus registers of the Schneider Electric EM6400NG, with the address on the wire, the 30001-style reference, data type, byte order, unit and scale. Transcribed from Public_PM2xxx_PMC Register List_v1001 (v1001).

EasyLogic EM6400NG power meter; measurements are 32-bit floats. Its registers come from the PM2100/PM2200 register list.

Connection notes

  • Every register here is a holding register (function code 3).
  • Addresses are Schneider's register numbers minus one, as for the PM5000 lists.
  • The source is register list v1001 (2016); Schneider publishes a newer list (v1050) for later firmware.
  • Unavailable values read as the N/A pattern of their type, e.g. 0xFFC00000 for FLOAT32.

Registers

Grouped as in the vendor document. Measurement, energy and identity groups are shown (126 registers); open any other group to load it.

Read the EM6400NG with an AI assistant

The Proxus Industrial MCP Server includes this map. Set it on the device, and Claude, Cursor or VS Code reads registers by key with the right type, byte order, scale and unit. It only reads.

This device speaks Modbus RTU: reach it through a Modbus TCP gateway and use the gateway’s address with the device’s unit ID.

Ask your assistant

Read current_a, current_b, current_c from em6400ng-1.

The tool call it makes

read_named(device: "em6400ng-1", keys: ["current_a", "current_b", "current_c"])

Have this device? Verify the map.

Ask your assistant to run verify_device_map. It reads every register once, read-only, checks that the values are plausible and asks you to compare two values with the display. You get a report and a prefilled GitHub issue to submit; your name goes on this map’s verified list.

Proxus reads Modbus TCP and RTU devices next to the machines, keeps the history and delivers the values to dashboards, databases and AI.
